200W 87.5-108MHz Adjustable FM Stereo Transmitter Full Protection Ham Radio

The 200W 87.5-108MHz Adjustable FM Stereo Transmitter is a powerful and reliable device designed for ham radio stations and broadcasting enthusiasts. With an adjustable power output up to 200W and a frequency range covering the full FM band (87.5-108MHz), this transmitter offers excellent audio quality and robust performance.

Equipped with a full protection design, it ensures safe operation with input voltage between 20V and 21V (max 26V) and a working current of 15A. The transmitter features a step frequency of 1kHz, low distortion (0.03%-0.1%), and a stereophonic separation degree greater than 40dB, delivering clear and crisp stereo sound.

With an output impedance of 50Ω and harmonic suppression below -60dBm, it guarantees minimal interference and high signal integrity. The transmission range exceeds 15 kilometers in open fields with a suitable antenna (sold separately), making it ideal for wide-area coverage.

The transmitter supports MP3 playback via SD card or external audio input, providing versatile audio source options. Its compact size (170x80x85mm) and weight (1100g) make it easy to install and integrate into existing setups.
